Abstract (en)
[origin: EP0090244A2] 1. Process for preparing triazinyl vat dyestuff mixtures which contain dyestuffs of the formulae see diagramm : EP0090244,P6,F1 and see diagramm : EP0090244,P6,F2 wherein A and B designate vattable radicals and R1 , R2 and R3 designate hydrogen, halogen, in particular Cl, Br or F, carboxyl, alkyl, in particular C1 -C6 -alkyl, and alkoxy, in particular C1 -C6 -alkoxy, characterised in that cyanuric chloride is reacted in a phenol of the formula see diagramm : EP0090244,P6,F3 with about 1.6 to about 2.4 mols of the amines A-NH2 and/or B-NH2 , essentially in the absence of compounds which have an alkaline reaction, at temperatures of about 80 to about 200 degrees C to give mixtures of compounds of the formulae I and II, and these mixtures are then isolated.
